Terry Collins hasn’t let the stress of two straight losing seasons to begin his Mets tenure diminish his fastball.

In an impassioned speech yesterday before the team’s first full-squad workout of spring training, the manager warned his players that winning is expected, regardless of the outside perception the Mets have too many holes to compete in 2013.

But instead of harping on the familiar underdog theme, the manager told his players how good they were, reminding them that 99 percent of participants at the amateur level never reach the major leagues.

“I don’t want them thinking it’s just about trying to prove people wrong,” Collins said. “I mean, you’re big league players.”

Collins later told The Post he wants the younger players to understand superstars such as Alex Rodriguez and Derek Jeter once made about $100,000 in salary and weren’t much different than them.
